Attempted Break-In on www.centos.org

On Friday evening, July 3rd (UTC) we found a few suspicious files on the CentOS webserver. Upon investigating we found out that the files had been put there through Xoops (the CMS www.centos.org runs on) - and that this was possible due to a an administrative error which has been corrected.

As far as we can see there has been no data or binary injected into the system or taken from the system. The machine hasn't been used as a source for sending spam (in the widest possible meaning) either...
